[0001] This utility model belongs to the field of depth sounder technology, specifically a depth sounder protection device. Background Technology

[0002] In many fields such as marine resource exploration, hydrological surveying, and aquaculture, accurate water depth measurement is a crucial task. As the core equipment for achieving this goal, the performance of the depth sounder directly affects the accuracy of the measurement data and the safety of the operation.

[0003] When a depth sounder is not in operation, its key components, the generator and receiver, are often exposed and easily damaged by impacts. Whether it is an accidental collision during transportation or a scrape with other objects in a complex field environment, it may cause the instrument to malfunction and affect subsequent measurement work. In the complex and ever-changing underwater environment, the frequent activities of underwater organisms, such as collisions with schools of fish and attachment of marine life, may also damage the instrument, reduce its service life, or even cause measurement work to be interrupted, increasing maintenance costs and time. Therefore, a depth sounder protection device is proposed to address the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-5 As shown, a depth sounder protection device includes: a supporting buoyancy plate 2, an mounting plate 10 is installed on the bottom side of the supporting buoyancy plate 2, and a generator 8 and a receiver 9 are installed side by side on the bottom side of the mounting plate 10;

[0027] A protective structure 6 is installed on the bottom side of the supporting buoyancy plate 2. The protective structure 6 includes a protective cover 61, which is fixed to the bottom side of the supporting buoyancy plate 2. The protective cover 61 is set around the generator 8 and receiver 9. As the main protective frame, the protective cover 61 can provide semi-enclosed protection for the generator 8 and receiver 9 to avoid damage from ordinary bumps. Support seats 67 are installed on the two opposing inner walls of the protective cover 61. Swing plates 68 are rotatably installed on the support seats 67 through pins. When the two swing plates 68 swing to a straight position, the bottom opening of the protective cover 61 can be closed by the cooperation of the two swing plates 68.

[0028] The side of the swing plate 68 and the side wall of the protective cover 61 are clearance fit structures, which can minimize the empty space between the swing plate 68 and the side wall of the protective cover 61 while ensuring that the swing plate 68 has space for swinging movement.

[0029] The top and bottom sides of the swing plate 68 are fixed with counterweight lead strips 66. The counterweight lead strips 66 are located on the side close to the magnetic strips 69. The top side of the swing plate 68 is fixed with magnetic strips 69. The two magnetic strips 69 are arranged in parallel alignment. The two counterweight lead strips 66 are arranged in parallel alignment. The counterweight lead strips 66 can increase the downward swing force of the swing plate 68. Under the cooperation of gravity, the two swing plates 68 can automatically swing downward. When the two swing plates 68 swing to a straight state, the two magnetic strips 69 are attracted by magnetic force.

[0030] A limiting baffle is provided on the bottom side of the swing plate 68, which limits the lowest swing point of the swing plate 68 to a straight state; it can limit the swing angle of the swing plate 68. When the swing plate 68 swings to a parallel structure, it means that the structure formed by the protective cover 61 and the two swing plates 68 can realize the protection of the generator 8 and the receiver 9. The two magnetic strips 69 have opposite magnetic properties. The two swing plates 68 have a double door structure at the bottom port of the protective cover 61. When the two magnetic strips 69 swing to the horizontal position, they are magnetically attracted to each other.

[0031] A slide rail 64 is vertically fixed to the outer side of the protective cover 61. A slider 62 is slidably installed inside the slide rail 64. A buoyancy airbag 63 is attached to the side of the slider 62. After the buoyancy airbag 63 enters the water, its buoyancy can pull the slider 62 to slide along the slide rail 64. A traction hole is opened on the side wall of the protective cover 61. A traction line 65 is inserted through the traction hole. The top end of the traction line 65 is fixed to the bottom side of the slider 62. The bottom end of the traction line 65 is fixed to the upper side of the swing plate 68 near the magnetic strip 69. The traction line 65 serves as a connecting component between the slider 62 and the swing plate 68, enabling the slider 62 and the swing plate 68 to move together.

[0032] The bottom of the slide rail 64 is provided with a groove for the traction line 65 to pass through and be limited. The traction line 65 moves along the groove, which can better limit the movement of the traction line 65.

[0033] The generator 8 and receiver 9 are installed vertically downwards, and the supporting buoyancy plate 2 is connected to the control display 1 via a connecting line 4.

[0034] When not in use, and the supporting buoyancy plate 2 is not submerged in water, the swing plate 68, under its own weight and the combined weight of the counterweight lead strip 66, swings downward around the pin shaft. With the cooperation of the bottom limiting baffle, when the two swing plates 68 swing to the contact of the limiting baffle, the two swing plates 68 are in a straight state. At this time, the two magnetic strips 69 attract each other. Through the attraction of the two magnetic strips 69, the bottom of the protective cover 61 is sealed by the two swing plates 68, which can provide protection for the generator 8 and the receiver 9 and prevent the generator 8 and the receiver 9 from being moved and damaged by collision.

[0035] In use, the supporting buoyancy plate 2 is submerged in water. In its floating state, the supporting buoyancy plate 2 is parallel to the water surface. All structures below the supporting buoyancy plate 2 are vertically submerged. After the buoyancy airbag 63 is submerged, it experiences an upward buoyancy force. This upward force is greater than the attraction force of the magnetic strip 69, the weight of the swing plate 68 itself, and the weight of the counterweight 66, causing the slider 62 to slide upward. With the assistance of the traction line 65, it pulls the swing plate 68. The swing plate 68 swings upward with the help of the pin, and the two swing plates 68 swing upward in an open-door shape. After the swing plate 68 swings, it can provide a working area for the generator 8 and the receiver 9. The generator 8 emits sound waves. After the sound waves encounter an obstacle, the reflected waves generated are received by the receiver 9. The sound emission time of the generator 8 and the reception time of the receiver 9 are recorded by the control display 1. Through the sound wave transmission rate and the filtering and screening module in the control display 1, the operation status of the generator 8 and the receiver 9 can also be operated through the control display 1. At the same time, the water depth is analyzed and calculated. The main body consisting of the control display 1, the generator 8 and the receiver 9 and other accessories is the EM2040P multibeam echo sounder.

[0036] A trigger structure 7 is installed on the top side of the supporting buoyancy plate 2. The trigger structure 7 includes a movable rod 72. An movable hole is opened inside the supporting buoyancy plate 2. The movable hole is located directly above one of the sliders 62. The movable rod 72 is movably arranged in the movable hole. The bottom end of the movable rod 72 is fixed above the slider 62. After the supporting buoyancy plate 2 enters the water, the slider 62 moves upward along the slide rail 64 under the buoyancy pull of the buoyancy airbag 63. After the slider 62 moves upward, it can slide into contact with the spherical electrode cap 75 and the elastic electrode plate 74 at the top. The top end of the movable rod 72 is fixed with the spherical electrode cap 75. A protective frame 73 is vertically arranged on the top side of the supporting buoyancy plate 2. The inner wall of the protective frame 73 is provided with the elastic electrode plate 74. The spherical electrode cap 75 and the elastic electrode plate 74 slide into contact.

[0037] A storage battery 3 is installed on the top side of the supporting buoyancy plate 2, and a light-emitting rod 71 is installed on the bottom side of the protective cover 61. The light-emitting rod 71 forms a circuit with the elastic electrode plate 74, the spherical electrode cap 75, and the storage battery 3. The light-emitting rod 71 serves as a waterproof light-emitting body and emits light underwater, which can disperse fish in the surrounding area.

[0038] In use, after the supporting buoyancy plate 2 is submerged in water, the slider 62 moves upward along the slide rail 64 under the buoyancy pull of the buoyancy airbag 63. After the slider 62 moves upward, the spherical electrode cap 75 at the top and the elastic electrode plate 74 can slide into contact. After the spherical electrode cap 75 and the elastic electrode plate 74 come into contact, the light rod 71 can be energized. It can drive away fish in the working area through light stimulation. The light tube of the light rod 71 is selected with a color of light that is stimulating to fish, which can reduce interference for water depth measurement and at the same time avoid underwater organisms from impacting and damaging the generator 8 and receiver 9, thus protecting the instrument during the depth measurement process.

[0039] Working principle: In order to test the depth sounder, when not in use, and when the supporting buoyancy plate 2 is not submerged in the water, the swing plate 68 swings down around the pin shaft under its own weight and the weight of the counterweight lead strip 66. With the cooperation of the bottom limit baffle, when the two swing plates 68 swing to the limit baffle and the two swing plates 68 are in a straight state, the two magnetic strips 69 attract each other. Through the attraction of the two magnetic strips 69, the bottom of the protective cover 61 is sealed by the two swing plates 68, which can provide protection for the generator 8 and the receiver 9 and prevent the generator 8 and the receiver 9 from being moved and damaged by collision.

[0040] In use, the supporting buoyancy plate 2 is submerged in water. While floating, the supporting buoyancy plate 2 is parallel to the water surface. All structures below the supporting buoyancy plate 2 are vertically submerged. After the buoyancy airbag 63 is submerged, it experiences an upward buoyancy force. This upward force is greater than the attraction force of the magnetic strip 69, the weight of the swing plate 68 itself, and the weight of the counterweight 66, causing the slider 62 to slide upwards. With the assistance of the traction line 65, it can pull the swing plate... The movable plate 68 and the swing plate 68 swing upward with the help of the pin shaft. The two swing plates 68 swing upward in an open door shape. After the swing plates 68 swing, they can provide a working area for the generator 8 and the receiver 9. The generator 8 emits sound waves. After the sound waves encounter an obstacle, the reflected waves generated are received by the receiver 9. The sound emission time of the generator 8 and the reception time of the receiver 9 are recorded by the control display 1. The water depth is calculated by analyzing the sound wave transmission rate and the filtering and screening module in the control display 1.

[0041] In use, after the supporting buoyancy plate 2 is submerged in water, the slider 62 moves upward along the slide rail 64 under the buoyancy pull of the buoyancy airbag 63. After the slider 62 moves upward, the spherical electrode cap 75 at the top and the elastic electrode plate 74 can slide into contact. After the spherical electrode cap 75 and the elastic electrode plate 74 come into contact, the light rod 71 can be energized. It can drive away fish in the working area through light stimulation. The light tube of the light rod 71 is selected with a color of light that is stimulating to fish, which can reduce interference for water depth measurement and at the same time avoid underwater organisms from impacting and damaging the generator 8 and receiver 9, thus protecting the instrument during the depth measurement process.
